Energy Network Automation
RTU for real time process monitoring and data collection
The FastNet is a compact RTU for
energy network automation. It can
be used for both data acquisition
and tele­control and also works as
­protocol converter and gateway.
Fully Configurable I/O
Digital outputs
The 14 digital outputs can be assigned
individually or in pairs. Select before
execute (SBE) mode is available when
an additional level of security is needed
to prevent erroneous operations. It can
be disabled to minimise communication
to the units when a narrow band
medium is deployed.
The digital outputs support both the
pulse and persistent modes. The pulse
times are individually configurable.
Digital inputs
The 18 digital inputs can be assigned
individually or in pairs. When they
are paired, on and off delays can be
configured such that the RTU will not
transmit the intermediate state when
the circuit breaker moves from one end
position to the other.
Typical Application Areas
• Medium voltage dis­connectors
• Secondary substations,
ring main units
• District heating
• Pumping stations
• Pole mounted reclosers
• Ring main units
• Diesel generator
• Cathodic protection
• Solar farms
• Wind farms
• District heating/cooling
• Pump Stations
• Biomass generation
Chatter control can be used to
prevent an input from continuously
sending change-of-state messages
when connected to faulty equipment.
Thus a single RTU cannot overload the
communication channel.
Digital outputs (14)
Analog inputs (8)
Analog inputs
The 8 analog inputs have selectable
sampling times and support a dead­
band, which reduces data traffic without
compromising performance.
A dip switch allows the user to select
between voltage- and current-based
measurement modes. The inputs can be
used for both AC and DC signals.
The analog measurements can be
averaged over configurable time periods.
Both scaling and offsets can be applied.
Versatile Communication
The FastNet supports a number of
communication options. It has one
RS‑485 connection, five RS‑232 ports
and an RJ45 port for 10/100 Ethernet.
One RS-232 port is reserved for service
and support and another, on the front
(top) panel, for configuration.
The FastNet can handle both

polled and event-triggered (or “report
by exception”) communication. Thus
a background health poll routine can
be supplemented with event-triggered
reporting. The individual inputs may
have different classes assigned to them
depending on whether they are to be
detected only during a health poll or also
when they change.
Port forwarding is available for all the
serial ports. It allows traffic to/from the
SCADA port to be sent transparently
through the RTU from/to a slave device.
Data Radio Option
The Fast Net RTU can be supplied with
the PDR data radio as a fully integrated

The inputs and
outputs have LED
indicators. They
are connected via
removable screw
terminals, which
make the isolation
and removal of a
FastNet RTU very
simple and quick.

telemetry solution. The PDR data
radio is a wide area device supporting
a fixed mesh configuration to allow
communication coverage over several
100's of Km2.
Support for key SCADA protocols
The FastNet supports the most
common SCADA protocols. The serial
IEC 60870‑5‑101 and Modbus RTU, the
IP-based IEC 60870-5-4‑104 and both
the serial and IP transport of DNP3 are
available.
The FastNet is configured either via the
RS-232 configuration port or with Telnet
over an Ethernet connection. The user
interface with its clear menu structure
makes the process straightforward.
The FastNet has an SD memory
card slot, which can be used to store
the entire configuration. It makes the
setup easy. Replacing units is as simple
as swapping a memory card from one
FastNet to the next. A large number of
FastNet units can be mass configured
with a ready made master configuration
file, ported via SD cards.
The memory card can also be
used to store an event log, allowing the
analysis of “sequence of events” data.
Multiple firmware upgrade options
The firmware can be upgraded through:
• the serial configuration port,
• FTP (File Transfer Protocol),
• an SD card or
• a separate TFTP (Trivial File Transfer
Program) server.
Easy I/O expansion
Modbus RTU Master support
The FastNet may be used as a Modbus
RTU master for up to 5 slave RTUs.
Six FastNet units can therefore be daisychained for additional I/O.
For SCADA communication Modbus
RTU can then be converted to one of
the other supported protocols.

The FastNet is designed to support
not only daisy chaining based on the
Modbus RTU Master functionality, but
also additional, “extended I/O” modules.
One option is to connect a maximum
of ten RTU-16D cards to the FastNet
through the Rbus interface. Each card
has 16 digital inputs and 16 digital
outputs. This puts the maximum of
digital inputs at 178 and that of digital
outputs, at 174.
